Help needed. Dimensions of the seater plug in a Lee Seating Die in 45/70

[stigfender]

I am looking into making a seater plug for wide flat nosed bullets. But I am away at work and do not have access to my reloading dies.

Is there anybody with this die available that could take some quick measurements for me?

I need the diameter of the plug, the diameter of the flange, the thickness of the flange and the overall length.

Any assistance would be much appreciated

Just order a seating plug from Lee and grind or file it flat. Done. I did so with my .38 spl plug because I only load wadcutters with it.

You could also fill your existing plug with epoxy. Same difference.

I know you can order a flat seating plug from Lee. The problem is I live in Norway. And every company I have had dealings with in Amerika demands ridiculous amounts in shipping! If the are willing to ship international.

I have axess to a lathe and suitable bar stock. So making on should be a doddle.

Just measure the one you have now. Then just make the contact point flat for the bullet.

He doesn’t have access to it, thus the thread.

Thanks @jmorris Just what I needed.

After a quick google on how to read a caliper marked in inches, I got the measurements How you guys manage with all those fractions

So i am interested to learn why the seating plug needs to be modified for an FN bullet. I load for 45-70, so even if the bullet is fully FN, will the die and plug adjusted correctly not allow for it to be seating to the desired depth?

I load mostly bullets with large meplats. And I have observed that if I am not very careful when seating the bullet (with my hands) into the belled mouth of the cartridge, the bullet is seated crooked. I think it is more likely that the bullet binds, and does not self-adjust when using a conventional seating plug.

Anyway. This is my reasoning for making a flat seating plug. Only testing will verify my hypothesis

Understood. Thanks for explaining and hope your modification resolves the issue.

Decimals inches are easier than fractions. Decimal inches is similar to the metric scales just a little different. Decimals are used for higher precision, fractions used in close enough.

With metric you normally go 2 decimal places x.xx. English std decimal for machine work is x.xxx or even x.xxxx

Maybe try READING post #1 again…
